Method Detail

getMaxTableCapacity

public int getMaxTableCapacity()

setMaxTableCapacity

public void setMaxTableCapacity(int maxTableSizeLimit)

Sets the limit for the capacity of the dynamic header table.

This value is set by the remote peer via the SETTINGS_HEADER_TABLE_SIZE setting.

Parameters:

maxTableSizeLimit - the limit for capacity of the dynamic header table

getTableCapacity

public int getTableCapacity()

setTableCapacity

public void setTableCapacity(int tableCapacity)

Sets the capacity of the dynamic header table.

The value of the capacity may be changed from 0 up to getMaxTableCapacity(). An HPACK instruction with the new capacity value will be sent to the decoder when the next call to encode(ByteBuffer, MetaData) is made.

Parameters:

tableCapacity - the capacity of the dynamic header table

getMaxHeaderListSize

public int getMaxHeaderListSize()

setMaxHeaderListSize

public void setMaxHeaderListSize(int maxHeaderListSize)

getHpackContext

public HpackContext getHpackContext()

setRemoteMaxDynamicTableSize

@Deprecated
public void setRemoteMaxDynamicTableSize(int maxTableSize)

Deprecated.

setLocalMaxDynamicTableSize

@Deprecated
public void setLocalMaxDynamicTableSize(int maxTableSizeLimit)

Deprecated.

isValidateEncoding

public boolean isValidateEncoding()

setValidateEncoding

public void setValidateEncoding(boolean validateEncoding)

encode

public void encode(java.nio.ByteBuffer buffer,
                   org.eclipse.jetty.http.MetaData metadata)
            throws HpackException

Throws:

HpackException

encodeMaxDynamicTableSize

                                      int maxTableSize)

encode

private void encodeName(java.nio.ByteBuffer buffer,
                        byte mask,
                        int bits,
                        java.lang.String name,
                        HpackContext.Entry entry)
